Note The count clock is set by the PRMn and PRMn1 registers.
Remark
f
XX
Generates an interrupt at predetermined time intervals.
Can output a square wave whose frequency and output pulse width can be changed arbitrarily.
Can measure the pulse width of a signal input from an external source.
Can measure the number of pulses of a signal input from an external source.
Can output a square wave of any frequency.
